It's hard to pick just one. If we're talking current, I'd have to pick either Cathy Heaven or Holly Michaels. Cathy for her oral skills and enthusiasm, Holly for her gorgeous face and 100% natural, 100% sexy body--AND her oral skills and personality.

If we're talking all-time, I can come up with a short list: Christy Canyon, Ginger Lynn, Heather Harmon (of ideepthroat fame) and Annette Schwarz.

If I have to pick just one, it'd be Annette, because of her amazonian (and again, 100% natural) sex appeal, her insatiable appetite and her unparalleled abilities. So sad she's retired--but what a great career!
